Moradvandi, A. (author), Lindeboom, R.E.F. (author), Abraham, E. (author), De Schutter, B.H.K. (author)Dynamical systems and processes that either exhibit non-smooth behaviours (e.g. through logic control or natural phenomena) or work in different modes of operation are usually represented using hybrid systems models, i.e. mathematical models that combine continuous dynamics with discrete-event dynamics. Identification of a hybrid system...conference paper 2023

Ubbens, Martiene (author), De Schutter, B.H.K. (author)Two optimization-based approaches are proposed to optimize the power routing and turbine setpoints of offshore wind farm (OWF) collector systems during cable outages. The open-loop control strategy assumes that the network can only be reconfigured at the beginning of the outage. In contrast, the receding horizon control strategy is deployed...conference paper 2023

Ilioudi, A. (author), Wolf, B.J. (author), Dabiri, A. (author), De Schutter, B.H.K. (author)The majority of computer vision architectures are developed based on the assumption of the availability of good quality data. However, this is a particularly hard requirement to achieve in underwater conditions. To address this limitation, plenty of underwater image enhancement methods have received considerable attention during the last...conference paper 2023

Daman, A. (author), Liu, X. (author), Dabiri, A. (author), De Schutter, B.H.K. (author)Timetables determine the service quality for passengers and the energy consumption of trains in metro systems. In metro networks, a timetable can be made by designing train departure frequencies for different periods of the day, which is typically formulated as a mixed-integer linear programming (MILP) problem. In this paper, we first apply...conference paper 2023

Remmerswaal, Willemijn (author), Sun, D. (author), Jamshidnejad, A. (author), De Schutter, B.H.K. (author)In general, the performance of model-based controllers cannot be guaranteed under model uncertainties or disturbances, while learning-based controllers require an extensively sufficient training process to perform well. These issues especially hold for large-scale nonlinear systems such as urban traffic networks. In this paper, a new...conference paper 2022

Liu, X. (author), Dabiri, A. (author), De Schutter, B.H.K. (author)Timetable scheduling plays a key role in daily operations of urban rail transit systems, as it determines the quality of service provided to passengers. In order to develop efficient timetable scheduling methods, it is necessary to develop a proper model to integrate timetable-related and passenger-related factors in urban rail network...conference paper 2022

Qiu, Xiujiao (author), Chen, J. (author), Ye, G. (author), De Schutter, Geert (author)ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...conference paper 2021

Yang, Kai (author), Ye, G. (author), De Schutter, Geert (author)Water molecules exist as two spin isomers, differing by the relative orientation of the nuclear spins of the two hydrogen atoms: either antiparallel (para-water, S=0) or parallel (ortho-water, S=1) [1]. The transition between these nuclear spin states can be achieved through magnetic symmetry breaking via a field gradient across the spins...conference paper 2021

de Gelder, E. (author), Cator, Eric (author), Paardekooper, Jan Pieter (author), Op den Camp, Olaf (author), De Schutter, B.H.K. (author)The safety assessment of Automated Vehicles (AVs) is an important aspect of the development cycle of AVs. A scenario-based assessment approach is accepted by many players in the field as part of the complete safety assessment. A scenario is a representation of a situation on the road to which the AV needs to respond appropriately. One way to...conference paper 2021

de Gelder, E. (author), Manders, Jeroen (author), Grappiolo, Corrado (author), Paardekooper, Jan Pieter (author), Camp, Olaf Op Den (author), De Schutter, B.H.K. (author)Scenario-based methods for the assessment of Automated Vehicles (AVs) are widely supported by many players in the automotive field. Scenarios captured from real-world data can be used to define the scenarios for the assessment and to estimate their relevance. Therefore, different techniques are proposed for capturing scenarios from real-world...conference paper 2020

Pippia, T.M. (author), Lago, Jesus (author), Coninck, Roel De (author), Sijs, J. (author), De Schutter, B.H.K. (author)In the context of building heating systems control in office buildings, the current state-of-the-art applies either a deterministic Model Predictive Control (MPC) controller together with a nonlinear model, or a linearized model with a stochastic MPC controller. Deterministic MPC considers only one realization of the external disturbances,...conference paper 2019

Dominguez Frejo, J.R. (author), De Schutter, B.H.K. (author)The main goal of this paper is the proposal and simulation of a SPEed limit controller for Recurrent Traffic jams (SPERT) that approximates the behavior of an optimal controller when congestion profiles are similar to the typical one. In order to achieve this goal, the optimal solution for the typical demand profile is computed and used as a...conference paper 2018

Siniscalchi-Minna, S. (author), De-Prada-Gil, M. (author), Bianchi, F. D. (author), Ocampo-Martinez, C. (author), De Schutter, B.H.K. (author)Nowadays, wind power plants (WPPs) should be able to dynamically change their power output to meet the power demanded by the transmission system operators. When the wind power generation exceeds the power demand, the WPP works in de-loading operation keeping some power reserve to be delivered into the grid to balance the frequency drop. This...conference paper 2018

Lago, Jesus (author), De Brabandere, Karel (author), De Ridder, Fjo (author), De Schutter, B.H.K. (author)In recent years, as the share of solar power in the electrical grid has been increasing, accurate methods for forecasting solar irradiance have become necessary to manage the electrical grid. More specifically, as solar generators are geographically dispersed, it is very important to have general models that can predict solar irradiance without...conference paper 2018

Picallocruz, M. (author), Anta, Adolfo (author), De Schutter, B.H.K. (author), Panosyan, Ara (author)In this paper we consider the problem of State Estimation (SE) in large-scale, 3-phase coupled, unbalanced distribution systems. More specifically, we address the problem of including mixed real-time measurements, synchronized and unsynchronized, from phasor measurement units and smart meters, into existing SE solutions. We propose a...conference paper 2018

Xu, J. (author), Buşoniu, Lucian (author), De Schutter, B.H.K. (author)We consider the infinite-horizon optimal control of discrete-time, Lipschitz continuous piecewise affine systems with a single input. Stage costs are discounted, bounded, and use a 1 or ∞-norm. Rather than using the usual fixed-horizon approach from model-predictive control, we tailor an adaptive-horizon method called optimistic planning for...conference paper 2017

Alavi, F. (author), van de Wouw, N. (author), De Schutter, B.H.K. (author)Recently, the idea of using fuel cell vehicles as the future way of producing electricity has emerged. A fuel cell car has all the necessary devices on board to convert the chemical energy of hydrogen into electricity. This paper considers a scenario where a parking lot for fuel cell cars acts as a virtual power plant. In order to describe the...conference paper 2016
